[Surgical Procedure of Buccal Mucosal Carcinoma - Reconstruction of Mouth Angle]

Surgical resection of the buccal mucosal carcinoma often induces soft tissue defect. The treatment plan should be considered to preserve oro-facial function and morpho-esthetics. This retrospective study reports the surgical reconstruction procedures in buccal mucosal carcinoma patients. We evaluated 4 cases(2 men, 2 women, mean age: 81.8 year-old)treated in Department of Oral and Maxillofacial Surgery, Shimane University Hospital between June 2007 and January 2017. The average size of primary tumor was 4.9 cm2. And the average size of facial skin defect in the mouth angle was 3.1 cm2. The facial local skin flaps and/or other pedicled flap were used for the reconstruction of the mouth angle. Severe contraction of the scar was manifested in 2 cases. Though reconstruction using the local pedicled flaps for full thickness skin defect in the mouth angle would be feasible, special attention is considered regarding the postoperative contraction of the scar.
